It was a complete knock-out.
The dull eyes, which looked up from the floor, saw nothing.

The square, rather brutal, face was relaxed as if in sleep, but here was the type of man who would recuperate with great speed.
Ronicky set about the obvious task which lay before him, as fast as he could.

In the man's coat pocket he found a handkerchief which, hard knotted, would serve as a gag.

The window curtain was drawn with a stout, thick cord.

Ronicky slashed off a convenient length of it and secured the hands and feet of his victim, before he turned the fellow on his face.
Next he went through the pockets of the unconscious man who was only now beginning to stir slightly, as life returned after that stunning blow.
It was beginning to come to Ronicky that there was a strange relation between the men of this house.
